No. 639,325 2 Claims. (Cl. 229-15) ABSTRACT OF THE DISCLOSURE Composite boxboard-plastic receptacles employing a boxboard body with relatively rigid transparent or translucent synthetic plastic ends, adhesively secured to the body, with the ends shaped to facilitate assembly and optionally having interior mounting provisions for articles, or partitions.

Background of the invention Field of the inventi0n.This invention relates to composite boxboard-plastic receptacles and more particularly to improved end constructions adherently secured to the receptacle body.

Description of the prior art.-It has heretofore been proposed to provide receptacles having a body with end caps adhesively or otherwise secured to the body. Usually such caps were of the same material as the body so that it was not possible to provide a transparent end panel. The prior receptacles of this type also, lacked adequate strength, such as has been available with receptacles having metal edges or stays.

It has also been proposed to provide a receptacle having end caps applied on a body but if a hinged lid or wall was desired no satisfactory locking provisions were available.

The receptacles with end caps applied on a body had numerous other disadvantages among which was the difficulty of assembly in quantities and by automatic machinery.

Summary of the invention It is the principal object of the present invention to provide a receptacle having a central body of boxboard, one portion of which is hinged for interior access, and having adherently secured end caps of synthetic plastic material, the end caps permitting viewing of the interior, if desired, and optionally having provisions for stilfening and for interior engagement with other objects.

It is a further object of the present invention to provide, in a receptacle of the character aforesaid, of improved access along the edges of the end caps for sealing.

It is a further object of the present invention to provide, in a receptacle of the character aforesaid, of interior mounting provisions for articles to be packaged.

It is a further object of the present invention to provide, in a receptacle of the character aforesaid, of end caps with inturned portions for supporting a cylinder which carries articles within the receptacle.

It is a further object of the present invention to provide in a receptacle of the character aforesaid, end caps having portions contributing to an auxiliary or additional receptacle.

It is a further object of the present invention to provide, in a receptacle of the character aforesaid, end caps which have portions supporting interior partitions.

Other objects and advantageous features of the invention will be apparent from the description and claims.

Description of the preferred embodiment Referring now more particularly to FIGS. 1, 2 and 3 of drawing, the receptacle there shown includes a body 15, preferably of boxboard, finished on one face and cut and creased to the desired size and shape.

The body 15, as herein shown, has a rectangular front wall panel 16 having a cut out 17 on one marginal edge -18 to facilitate opening and closing.

The front wall panel 16 has connected thereto along a crease line 19, a rectangular bottom wall panel 20.

The bottom wall panel 2 0 has, connected thereto along a crease line 21, a rectangular rear wall panel 22 and the rear wall panel 22 has, connected thereto along a crease line 23 which serves as a hinge, a rectangular top wall panel 24.

The top Wall panel 24 has connected thereto, along a crease line 25, a front flap 26. The front flap v26 is adapted to be disposed inwardly along the front wall panel 16 in the closed condition of the receptacle and has set backs 27 at each side.

The ends of the tube provided by the wall panels 16, 20, 22 and 24, are preferably closed by end elements 28 which may be of dished shaped described, and preferably are of synthetic plastic material premolded before assembly to the body 15. The end elements 28 can be of any desired color or colors, and embossed or debossed for descriptive purposes, if desired. Any desired synthetic plastic material may be used provided it is capable of being adhered to the material of the body as hereinafter referred to. One suitable material is a vinyl plastic.

The end elements 28 may be of transparent or opaque material, dependent upon the field of use, but for certain purposes at least one end element 28 is transparent.

As shown in FIGS. 1, 2 and 3 the end elements 28 have outer rims 30 one or more of which may function as a hinged glue flap which may be connected at their meeting locations, may be separated at the crease line 23 where the top wall panel 24 extends from the rear wall panel 22 at each end to permit the hinging of the top wall panel 24 at this location with the top wall panel 24 disposed above the contiguous rim 30 in closed position, or if connected at their meeting locations may extend into slits (not shown) at the ends of the crease line 23.

The rims 30 extend from and are integral with a central panel portion 31 which preferably includes inner rim portions 32 parallel to the rims 30 and spaced therefrom to receive the ends of the wall panels 16, 20 and 22. The central panel portions 31 also includes corner panels 33, and a central panel 34 framed by flat marginal panels 35 and inclined margins 36. This shape adds to the rigidity of the end element 28. The elongated simultaneous access, available to rim 30 and inner rim portions 31 permits of the application of heat and pressure therealong from one or both sides as hereinafter pointed out.

The crease line 25, at its ends, has slots 38 to provide with the set backs 27, a lock from the top Wall panel 24 by engagement of the rims 30 in the slots 38, the flap 26 resiliently yielding to permit locking and release.

Referring now to FIGS. 4 and the body there shown is similar to that previously described except for a different shape of cutout 17a in the marginal edge 18.

The central panel portion 31a preferably has framing panel portions 39 and vertically extending alternating flat face portions 40, in the same plane as or inwardly of the plane of the panel portions 39, and inwardly extending arcuate grooves 41, to increase the stiffness.

Referring now to FIGS. 6 and 7, the central panel por tion 31b preferably has a central inwardly extending circular flange 43 which with the corresponding flange 43 at the opposite end provides a support for a cylindrical tube 44. The tube 44 can serve as a support for various articles (not shown) such as bandages, tape, ribbon or the like. The interior of the tube 43 can be closed, to provide an auxiliary receptacle, by end closure caps 45 in frictional engagement in the flange 43.

Referring now to FIGS. 8, 9 and 10, the body 15 there shown, is similar to that previously described but different end elements 28c are employed.

The end elements 28c have rim portions 30 and an outer frame 48 against the inner face of which the ends of the wall panels 16, and 22 engage.

The central panel portion 310 of the end elements 28c have a plurality of hollow vertical ribs 49 which receive slidably inserted vertical spacers 50 for separating the interior into a plurality of compartments. The outer faces 51 of the ribs preferably are in a plane inwardly of the plane of the frame 48.

The end elements 28 in their various configurations as shown in FIGS. 1 to 10, inclusive, are preferably applied to the body 15 in any desired manner and are secured thereto by a suitable adherent action either derived from the plastic, if a plastic capable of heat sealing is employed, or by the use of a suitable heat responsive adhesive which may be applied over the entire surface of the box body 15 for use at the location engaged by the rims 30, or by stripes applied along those portions of the body 15 engaged by the rims 30, the rims 30 being secured either exteriorly or interiorly as desired.

In the form of receptacle shown in FIGS. 4 to 10, inclusive, an interior mandrel (not shown) may be employed so that upon the application of heat and pressure on the rims 30 at their locations in engagement with the wall panels 16, 20 and 22, a firm adherent engagement will be obtained at these locations.

The construction shown in FIGS. 1, 2 and 3, permits of squeeze engagement of the inner rim portions 32 and rims 30 for the application of heat and pressure for obtaining the desired adherence.

It will thus be seen that receptacles have been provided for carrying out the objects of the invention.

I claim:

1. A receptacle comprising a body of boxboard having a plurality of panels, providing enclosing walls on four sides,

end elements of synthetic plastic at the ends of said body having rims respectively adhesively engaged with a plurality of said wall panels,

one of said panels being hinged with respect to said body and being movable into receptacle closing relation with respect to said other walls,
